From: Mikko Rasa Date: Mon, 1 Feb 2021 19:08:29 +0000 (+0200) Subject: Separate abstract pixel compositions from concrete pixel formats X-Git-Url: http://git.tdb.fi/?a=commitdiff_plain;h=9087cc0;p=libs%2Fgl.git Separate abstract pixel compositions from concrete pixel formats Texture and renderbuffer storage must now be specified using a sized pixel format. The PixelFormat API has also been refactored. --- diff --git a/extensions/msp_luminance_formats.glext b/extensions/msp_luminance_formats.glext new file mode 100644 index 00000000..c513e084 --- /dev/null +++ b/extensions/msp_luminance_formats.glext @@ -0,0 +1 @@ +extension MSP_luminance_formats diff --git a/gl.msp.xml b/gl.msp.xml index 0309a61d..7895a806 100644 --- a/gl.msp.xml +++ b/gl.msp.xml @@ -45,5 +45,14 @@ + + + + + + + + + diff --git a/source/ambientocclusion.cpp b/source/ambientocclusion.cpp index 8826964a..b1dccc0e 100644 --- a/source/ambientocclusion.cpp +++ b/source/ambientocclusion.cpp @@ -12,7 +12,7 @@ namespace Msp { namespace GL { AmbientOcclusion::AmbientOcclusion(unsigned w, unsigned h, float): - occlude_target(w, h, (RENDER_COLOR,RED)), + occlude_target(w, h, (RENDER_COLOR,R8)), occlude_shader("ambientocclusion_occlude.glsl"), combine_shader("ambientocclusion_combine.glsl"), quad(get_fullscreen_quad()) @@ -21,7 +21,7 @@ AmbientOcclusion::AmbientOcclusion(unsigned w, unsigned h, float): texturing.attach(2, occlude_target.get_target_texture(RENDER_COLOR)); unsigned seed = 1; - rotate_lookup.storage(RGBA, 4, 4, 1); + rotate_lookup.storage(RGBA8, 4, 4, 1); rotate_lookup.get_default_sampler().set_filter(NEAREST); unsigned char data[64]; for(unsigned i=0; i<16; ++i) diff --git a/source/colorcurve.cpp b/source/colorcurve.cpp index 8983df2b..1f6f7bf9 100644 --- a/source/colorcurve.cpp +++ b/source/colorcurve.cpp @@ -18,7 +18,7 @@ ColorCurve::ColorCurve(): shdata.uniform("source", 0); shdata.uniform("curve", 1); - curve.storage(LUMINANCE, 256, 1); + curve.storage(LUMINANCE8, 256, 1); Sampler &sampler = curve.get_default_sampler(); sampler.set_min_filter(LINEAR); sampler.set_wrap(CLAMP_TO_EDGE); diff --git a/source/datatype.h b/source/datatype.h index 0d52408a..2d783f61 100644 --- a/source/datatype.h +++ b/source/datatype.h @@ -2,6 +2,7 @@ #define MSP_GL_DATATYPE_H_ #include "gl.h" +#include namespace Msp { namespace GL { @@ -14,9 +15,12 @@ enum DataType UNSIGNED_SHORT = GL_UNSIGNED_SHORT, INT = GL_INT, UNSIGNED_INT = GL_UNSIGNED_INT, - FLOAT = GL_FLOAT + FLOAT = GL_FLOAT, + HALF_FLOAT = GL_HALF_FLOAT }; +unsigned get_type_size(DataType); + } // namespace GL } // namespace Msp diff --git a/source/environmentmap.cpp b/source/environmentmap.cpp index ac68ff99..f4000c76 100644 --- a/source/environmentmap.cpp +++ b/source/environmentmap.cpp @@ -17,11 +17,11 @@ EnvironmentMap::EnvironmentMap(unsigned s, Renderable &r, Renderable &e): update_interval(1), update_delay(0) { - env_tex.storage(RGB, size, 1); + env_tex.storage(RGB8, size, 1); Sampler &env_samp = env_tex.get_default_sampler(); env_samp.set_wrap(CLAMP_TO_EDGE); env_samp.set_min_filter(LINEAR); - depth_buf.storage(DEPTH_COMPONENT, size, size); + depth_buf.storage(DEPTH_COMPONENT32F, size, size); for(unsigned i=0; i<6; ++i) { fbo[i].attach(COLOR_ATTACHMENT0, env_tex, TextureCube::enumerate_faces(i), 0); diff --git a/source/pipeline.cpp b/source/pipeline.cpp index 26073549..a7f4130b 100644 --- a/source/pipeline.cpp +++ b/source/pipeline.cpp @@ -234,7 +234,7 @@ void Pipeline::create_targets(unsigned recreate) target_ms = 0; } - PixelFormat color_pf = (hdr ?
